I mean the first ROI in the ROI Manager, not the first identified by roiIndex array.

If roiIndx length is 5, code chooses 2 ROIs, the second one the third one. the array will be something like (1,2,0,0,0)

The first one (index of 0) is always chosen.

Hello Lai,

the first index in the array is always marked in the image.
All indices in the array are selected in the list.

newArray(0,3,5) will mark the first list Roi in the image.
newArray(3,0,5) will mark the fourth list Roi in the image.

What exactly do you want to work around?

Have you check the 'Show all' option?

Regards,

Peter
